 Remember the cassette tape? No skipping through songs easily, but hitting that fast-forward button and, oh, no, it's eating the tape. Yeah, kids, that was actually a thing. Well, cassette tapes are back, not like more than streaming, but, for example, Taylor Swift's new album, The Tortured Post Department, sold more than 21,000 tapes the first week. Blame 13 Reasons Why, Stranger Things, or maybe even Guardians of the Galaxy's awesome mix, but cassettes are definitely on the radar again for kids today. Why?
